cultur’d: what genius + autism have in common…

A study of eight child prodigies finds that share some striking characteristics, most notably high levels of autistic traits and an overrepresentation of autism in their close family members.

Child prodigies evoke awe, wonder and sometimes jealousy: how can such young children display the kinds of musical or mathematical talents that most adults will never master, even with years of dedicated practice? Lucky for these despairing types, the prevailing wisdom suggests that such comparisons are unfair — prodigies are born, not made (mostly). Practice alone isn’t going to turn out the next 6-year-old Mozart.

So finds a recent study of eight young prodigies, which sought to shed some light on the roots of their talent. The prodigies included in the study [PDF] are all famous (but remain unidentified in the paper), having achieved acclaim and professional status in their fields by the ripe age of 10. Most are musical prodigies; one is an artist and another a math whiz, who developed a new discipline in mathematics and, by age 13, had had a paper accepted for publication in a mathematics journal. Two of the youngsters showed extraordinary skill in two separate fields: one child in music and art (his work now hangs in prestigious galleries the world over), and the other in music and molecular gastronomy (the science behind food preparation — why mayonnaise becomes firm or why a soufflé swells, for example). He became interested in food at age 10 and, by 11, had carried out his first catering event.

All of the prodigies had stories of remarkable early abilities: one infant began speaking at 3 months old and was reading by age 1; two others were reading at age 2. The gastronomist was programming computers at 3. Several children could reproduce complex pieces of music after hearing them just once, at the age most kids are finishing preschool. Many had toured internationally or played Lincoln Center or Carnegie Hall well before age 10.

Six of the prodigies were still children at the time of the study, which is slated for publication in the journal Intelligence. The other two participants were grown, aged 19 and 32.

The study found a few key characteristics these youngsters had in common. For one, they all had exceptional working memories — the system that holds information active in the mind, keeping it available for further processing. The capacity of working memory is limited: for numbers, for example, most people can hold seven digits at a time on average; hence, the seven-digit phone number. But prodigies can hold much more, and not only can they remember extraordinarily large numbers, they can also manipulate them and carry out calculations that you or I might have trouble managing with pencil and paper.

Working memory isn’t just the ability to remember long strings of numbers. It is the ability to hold and process quantities of information, both verbal and non-verbal — such as, say, memorizing a musical score and rewriting it in your head. All the children in the study scored off the charts when tested on measures of working memory: they placed in at least the 99th percentile, with most in the 99.9th percentile.

Surprisingly, however, the study found that not all of the prodigies had high IQs. Indeed, while they had higher-than-average intelligence, some didn’t have IQs that were as elevated as their performance and early achievements would suggest. One child had an IQ of just 108, at the high end of normal.

There was something else striking too. The authors found that prodigies scored high in autistic traits, most notably in their ferocious attention to detail. They scored even higher on this trait than did people diagnosed with Asperger’s syndrome, a high-functioning form of autism that typically includes obsession with details.

Three of the eight prodigies had a diagnosed autism spectrum disorder themselves. The child who had spoken his first words at 3 months, stopped speaking altogether at 18 months, then started again when he was just over two-and-a-half years old; he was diagnosed with autism at 3. What’s more, four of the eight families included in the study reported autism diagnoses in first- or second-degree relatives, and three of these families reported a total of 11 close relatives with autism. In the general population, by contrast, about 1 in 88 people have either autism or Asperger’s.

Other unusual parallels between prodigies and those with autism: they’re both more likely to be male (though that finding may be due in part to the failure to recognize either girls on the autism spectrum or, perhaps, girls’ hidden talents) and both are associated with difficult pregnancies, suggesting that uterine environment may play a role in their development. In the math whiz’s case, for example, his mother “started labor nine times between the 29th and 37th weeks of her pregnancy and required medication to stop the labor. During the 35th week of her pregnancy, her water broke and she had a 105-degree fever from an infection in her uterus. The child prodigy did not have a soft spot at delivery,” the authors write. read more..
